Array Purpose; Table 12. Factors To Consider For Array Configuration - Intel SC5650BCDP Software User's Manual

Array Purpose

Important factors to consider when creating RAID arrays include availability, performance,
and capacity. Define the major purpose of the disk array by answering questions related to
these factors, such as the following, which are followed by suggested RAID levels for each
situation:

Will this disk array increase the system storage capacity for general-purpose file and
print servers? Use RAID 5, 6, 10, 50, or 60.
